The Tasmanian Logistics Committee is calling on the State Government to ensure safe passage of goods through Victorian ports - even in the case of industrial action.

Earlier this year freight transport ground to a standstill while wharf workers staged an illegal protest against the sacking of one of their fellow workers.

At any other time of year it would have led to millions of dollars worth of fresh produce going to waste, and the Logistics Committee wants to see that that never happens.

Chairman Steve Henty said Tasmania is responsible for 28 per cent of traffic through Victorian ports and that the Logistics Committee is concerned at the amount of time it took to clear the wharf when action was staged in July 2013.

"The delay in any action to clear the wharf could have a detrimental effect on business here in Tasmania," he said.

"If this had have happened during a peak period, particularly near Christmas or around Easter, there would have been a number of days there would have been a number of freight vessels that could not cross the Bass Straight.

"It would have been devastating for not only the south-bound product coming into Tasmania, but the significant number of perishable goods that come north from Tasmania," he said.

The Committee has written to the Tasmanian Government to ask that an emergency plan be put in place to protect the Tasmanian economy in future.

If there was a protest on another highway between two different states we think there would have been more action taken

"What we want is an understanding that this is the only access that Tasmania has to freight and passenger vehicles have to the mainland.

"We don't have any other way around, we can't choose to go to another port.

"If there was a protest on another highway between two other states we think there would have been more action taken," he said.

"We want an understanding between the Victorian Government and ports, and the Tasmanian Government, so that we recognise that this is a key freight corridor for Tasmanian freight, and a lifeline for the Tasmanian economy."

"We're asking for three main things," he said.

"To have an emergency action plan that insulates Tasmanian freight from industrial action across the port of Melbourne.

"To then provide any details of an emergency plan to the Victorian government and get cooperation and an undertaking from the ports, from the government both Victorian and Tasmanian, and the maritime movement, that clearly allows for the movement of freight," he said.

The Tasmanian government has acknowledged to the Committee that it has received the letter.

The Minister for Infrastructure David O'Byrne declined to comment but a spokesperson said the government is committed to working through the issue.
